We highly recommend reading our previous blogs about Xloader in order to get a better understanding of the malware’s internals.
This multi-stage fileless Remcos RAT attack leverages a phishing-delivered JavaScript dropper to trigger a reflective PowerShell loader that executes payloads entirely in memory. The infection chain utilizes obfuscation techniques like rotational XOR and Base64 encoding to reconstruct .NET payloads, significantly reducing the disk-based detection footprint. Stealth is maintained by using aspnet_compiler.exe as a LOLBin to proxy malicious execution and dynamically retrieving the final payload from a remote C2 server.
On March 31, NSFOCUS CERT detected that the npm repository of the HTTP client library Axios was poisoned by the supply chain. The attacker bypassed the normal GitHub Actions CI/CD pipeline of the project, changed the account email address of the axios maintainer to an anonymous ProtonMail address, and manually released a malicious version with a Trojan backdoor through the npm CLI. When the user installs it, a persistent remote control will be established on the host. The impact is wide-ranging, and relevant users are requested to take measures for investigation and protection as soon as possible.
This is the fifth update to the TeamPCP supply chain campaign threat intelligence report, "When the Security Scanner Became the Weapon" (v3.0, March 25, 2026). Update 004 covered developments through March 30, including the Databricks investigation, dual ransomware operations, and AstraZeneca data release. This update consolidates two days of intelligence through April 1, 2026.
The Axios NPM package was compromised through a supply chain attack attributed to North Korean threat actors. Attackers exploited a long-lived NPM access token to bypass GitHub Actions' OIDC-based CI/CD publishing workflow, enabling them to push backdoored versions of the package. This breach allows malicious code to be distributed to developers and applications relying on Axios, a widely used HTTP client library in JavaScript environments. Although no known exploits in the wild have been reported yet, the potential for widespread impact exists due to Axios's extensive use in web and mobile applications. The attack highlights vulnerabilities in CI/CD pipeline security and token management. Mitigation requires immediate revocation of compromised tokens, strengthening CI/CD authentication mechanisms, and vigilant monitoring of package integrity. Countries with significant software development sectors and heavy reliance on JavaScript ecosystems, including the United States, India, Germany, South Korea, Japan, and the United Kingdom, are most at risk. Given the ease of exploitation and potential for supply chain compromise, the severity is assessed as high despite the current low severity rating. Defenders must prioritize securing CI/CD workflows and verifying package authenticity to prevent similar attacks.
A sophisticated malware campaign targeting WhatsApp users has been observed since February 2026. The attack chain begins with malicious Visual Basic Script files sent via WhatsApp messages, which, when executed, initiate a multi-stage infection process.
